The Annual Survey of Hours and Earnings (ASHE) low pay estimates for April 2012 show that:
There were 287 thousand jobs with pay less than the national minimum wage held by people aged 16 and over. This constitutes 1.1 % of UK employee jobs.
There were 18 thousand jobs held by 16 to 17-year-olds (6.5 % of jobs in this age group) with pay less than £3.68 per hour.
For 18 to 20-year-olds, there were 58 thousand jobs with pay less than £4.98 per hour (5.2 % of jobs in this age group).
For employees aged 21 and over, there were 211 thousand jobs with pay less than £6.08 per hour (0.9 % of jobs held by those in this age group).
The national minimum wage (NMW) is a minimum amount per hour that most workers in the UK are entitled to be paid. There are different levels of NMW depending on a worker's age and whether they are an apprentice.
People in part-time work were nearly twice as likely as people in full-time work to be paid less than the minimum wage, with 1.7 % of part-time jobs and 0.9 % of full-time jobs falling below the minimum wage. Jobs held by women were more likely to be paid less than the minimum wage than jobs held by men (1.3 % compared with 0.9 %). This is consistent with the fact that a greater proportion of women work part-time than men.
The figures for 2012 show an increase of 16 thousand jobs with pay less than the national minimum wage compared with the estimates for 2011.
|Age 16–17||Age 18–21||Age 22 and over||All jobs|
|Age 16–17||Age 18–20||Age 21 and over||All jobs|
Rate is £3.80 per hour (aged 18–21) or £4.50 per hour (aged 22 and over).
Rate is £3.00 per hour (aged 16–17) or £4.10 per hour (aged 18–21) or £4.85 per hour (aged 22 and over).
Rate is £3.00 per hour (aged 16–17) or £4.25 per hour (aged 18–21) or £5.05 per hour (aged 22 and over).
Rate is £3.30 per hour (aged 16–17) or £4.45 per hour (aged 18–21) or £5.35 per hour (aged 22 and over).
Rate is £3.40 per hour (aged 16–17) or £4.60 per hour (aged 18–21) or £5.52 per hour (aged 22 and over).
Rate is £3.53 per hour (aged 16–17) or £4.77 per hour (aged 18–21) or £5.73 per hour (aged 22 and over).
Rate is £3.57 per hour (aged 16–17) or £4.83 per hour (aged 18–21) or £5.80 per hour (aged 22 and over).
Rate is £3.64 per hour (aged 16–17) or £4.92 per hour (aged 18–20) or £5.93 per hour (aged 21 and over).
Rate is £3.68 per hour (aged 16–17) or £4.98 per hour (aged 18–20) or £6.08 per hour (aged 21 and over).
For years prior to 2004, the survey did not include additional samples introduced to improve the ASHE coverage. Therefore, to yield the best available low pay estimate the ASHE-based estimate must be combined with the Labour Force Survey (LFS). Estimates for 1998 to 2003 provided by the central estimate of the ASHE and LFS are given below.
|Age 18–21||Age 22 and over||All jobs|
Figures for Spring 1998, before the national minimum wage was introduced, are for the number of jobs paid at less than £3.00 per hour (aged 18–21) or £3.60 per hour (aged 22 and over).
Rate is £3.00 per hour (aged 18–21) or £3.60 per hour (aged 22 and over).
Rate is £3.20 per hour (aged 18–21) or £3.70 per hour (aged 22 and over).
Rate is £3.50 per hour (aged 18–21) or £4.10 per hour (aged 22 and over).
Rate is £3.60 per hour (aged 18–21) or £4.20 per hour (aged 22 and over).
The ASHE is based on a sample of employee jobs taken from HM Revenue & Customs (HMRC) Pay As You Earn (PAYE) records. Information on earnings and hours is obtained from employers and treated confidentially. ASHE does not cover the self-employed nor does it cover employees not paid during the reference period. In 2012 information related to the pay period which included 18 April.
This release contains summary earnings statistics from the 2012 Annual Survey of Hours and Earnings (ASHE). More detailed information is available on the National Statistics web site.

Common pitfalls in interpreting the series
Although the low pay estimates attempt to measure the number of jobs that are paid below the national minimum wage, it should be noted that the estimates cannot be used as a measure of non-compliance with the legislation. This is because it is not possible to determine from the survey data whether an individual is eligible for the minimum wage. For example, it is not possible to identify people such as apprentices and those undergoing training who are exempt from the minimum wage rate or are entitled to lower rates. In addition, if employees receive free accommodation, employers are entitled to offset hourly rates.
The low pay estimates presented relate to gross pay excluding overtime before tax, National Insurance or other deductions, and exclude payments in kind. The results are limited to earnings relating to the survey pay period and so exclude payments of arrears from another period made during the survey period. Any payments due as a result of a pay settlement but not yet paid at the time of the survey will also be excluded.
Published low pay estimates do not include those employees whose earnings in the pay period were affected because of absence from work.
Full-time employees are defined as those who work more than 30 paid hours per week or those in teaching professions working 25 paid hours or more per week.
This bulletin only gives estimates of the total number of jobs paid below the national minimum wage by sex or age band. More detailed estimates, including the UK distribution by 10p bands and analyses by occupation, industry and regions, are given for years 1998 to 2012 in the reference tables included in the Low Pay - April 2012 release.
UK legislation covering minimum wage rates for employees over the age of 18 was introduced on 1 April 1999. In October 2004 a national minimum rate was introduced for 16 to 17-year-olds. Since their introduction the national minimum wage rates have been regularly reviewed. In October 2010 the age at which employees are entitled to the main national mimimum wage rates was changed from 22 years old to 21 years old. Details of the different wage rate levels are given in the following table.
|Aged 16–17||Aged 18–21||Aged 22 and over|
|Apr 1999–May 2000||£3.00||£3.60|
|Jun 2000–Sep 2000||£3.20||£3.60|

In line with normal practice this release contains revised estimates for the number of jobs paid below the national minimum wage from the 2011 survey results, which were first published on 23 November 2011. These estimates take account of some corrections to the original 2011 ASHE data that were identified during the validation of the results for 2012, as well as late returns.
Low pay estimates for 2011 have been revised down by 25 thousand jobs.
Both the 2012 Low Pay estimates and the revised 2011 Low Pay estimates will be made available from 22 November 2012.
Coefficient of Variation
The coefficient of variation (cv) is the ratio of the standard error of an estimate to the estimate, expressed as a percentage. The smaller the cv value the higher the quality of the estimate. The coefficients of variation for estimates of UK jobs paid below national minimum wage in April 2012 are shown in the table below:
|Estimate||Coefficient of variation|
|21 years and over||211||2.6|
|All over 16 years||287||2.3|
The 2012 ASHE is based on approximately 182 thousand returns.
ASHE - LFS central estimates 1998 - 2003
For 1998–2003, the average of the ASHE and the Labour Force Survey (LFS) estimates (the ‘central estimate’) has been taken as the best available indication of the number of jobs paid below the national minimum wage. This is because the ASHE cannot stand alone as the source for low pay estimates without the additional samples introduced in 2004 to improve its coverage. For comparison, the estimate for low pay jobs in 2004 is 276 thousand with the additional samples, and 270 thousand with the central estimate.
The LFS collects information on the earnings, and normal and actual hours worked, of about 15 thousand people aged 16 and over each quarter. In addition it collects data on a wide range of personal characteristics, including education level and ethnic origin. This enables the preparation of statistics on levels and distribution of earnings similar to the ASHE but with lower precision due to the much smaller sample size.

The percentage changes of constituent items in tables may not always agree exactly with the values shown due to rounding.
